Features:The product is designed by using AD8317 chip, and is used for RF signal power detection.Can detect power in -55dBm to 0dBm of an RF signal, so that the RF signal is converted to DC voltage output. It can be widely used in radio frequency signal detection, signal power measurement, environmental field strength detection.It can also be used as part of automatic gain control and automatic level control.Application: RF transmitter PA set point control and level monitoring; Power monitoring in a radio line transmitter; RSSI measurements in base stations, WLAN, WiMAX, and radarSpecification:Input impedance: 50 OhmsOutput impedance: 50 Ohms (video impedance)Working frequency Freq: 1MHz ~ 10GHzInput/output ratio: 22mv /dBmInput dynamic range: -60 ~ +5dBm (high linear dynamic range: -55 ~ 0 dBm)Size: 6.5*3.5cm/2.6*1.4inWeight: Approx.9g/0.3ozPackage list:1 x Logarithmic Power Meter
